CMS has released the 2025 ICD-10-CM diagnosis code tables, the ICD-10-CM Coding Guidelines, and updated ICD-10-PCS procedure code tables and index and Addendum.


It is important to annually review the ICD-10-CM Official Guidelines for Coding and Reporting as “these guidelines have been developed to assist both the healthcare provider and the coder in identifying those diagnoses that are to be reported. The importance of consistent, complete documentation in the medical record cannot be overemphasized. Without such documentation accurate coding cannot be achieved. The entire record should be reviewed to determine the specific reason for the encounter and the conditions treated.”


When reading the guidelines, look for what is new and for when the guidelines indicate that you should query the provider if documentation is unclear. Finally, be sure to share this information with your Coding and Clinical Documentation Integrity staff as part of their preparedness plan for the October 1st start of the 2025 CMS Fiscal Year.
